(enteran nanna una ser er i To all?, when?, t may concern-i Beit knownthat'l, Winnen Sonnen, a

citizen of the United-States, and legal resi .'dentof Salem,'county ofl/'asliingtom State 4ot lndiana, have invented certain new and usefulImprovements in Dimensional Meas` uring Devices, of which the followingis a specification.

` #The invention herein described may' be used by the Government or anyof its otiicers or employees, or by any other person in the UnitedStates, in the prosecution otwork for the Government, without paymentVof any royalty thereon.

This invention is aldim'ensionalmeasuring.

device designed more particularly for use in measuring dimensionsof'objects' not readily adjustable between the calipering elements of anapparatus. j

The device is especially adapted for the measurement oi children,particularly infante, although it is to be understood that its uses arenot limited to such measurements. Inthe treatment o some cliildrnsdiseases, such for example as rickets, it may be desirous to ascertainaccuratelyfrom time totiinel the measurements o the child to de? terminethe progress o the diseases' With young infants suffering frommalnutrition `it has been found diiiicult teaccurately placethem on adevice in a den'ite'positionfrom which measurements are `to be nade fromtime to time Jfor comparative purposes. Moreover, if the child isrestless,`accurate measurements from a fixed dimension limitor'indicator are almost impossible, Adue to a lack of contact or ofuniform pressure atthe limit indicator, or to inaccuracy. o placing' thechild on the support, as well as the time.

necessary to make the various preliminary adjustments prior todetermining the -final measurements., j

A purpose of this invention is to provide means that will permit ofuniform, denit'e and simultaneous adjustments wherebytlie necessarymeasurements' may be quickly and accurately 'made without the necessityof placing theobiect toloe 'measured at any definite or predetermined'position' upon the measuring apparatus. l

Thev elementgB is preferably so mounted with relation-to thebase Athat it has a limited orstopgmovfement in contact with the'he'adlof the basev member indicated at D. g The movable element Bis slidablymounted on the base A by means ofQthe plate F 4fittingloosely 'in a'hert or longitudinal groove` f formed'inthe base A. This plate ispreferably rigidly secured to the head element B and is jpre`- sis lec

It is therefore toaccurately` place the infant upon any particular part of the bafie A,but it is preferable that the head of the infant l' shall besubstantially coincident with the upper edge D or head of the base A.The child is placed in a reclining-position and when that position hasbeen assumed the operator will press the element C toward the feet ofthe child with one hand, and draw the head element B by means of thescale plate F,- toward the head of the child, therebyobtaining quicklyand accurately a delin'ite measurement of the length-of the childindicated upon the scale 4 by the indicator E. It will Abe observed thatthe caliperinpr or looperating. elements B, C/niay be movedsinilliltaneously by the two hands of the operatpr; that it isnotnecessary to place the infant tobe measured at any definite positionupon the base or supporting element A;

that non-uniform pressure or lack of Contact of one of the elements B orC, rdue to inaccuracy of the support, has been eliminated in a device ofthis ,character Where both of the elements are movable toward the objectto be measured. Where one of the elements, forexample B, is' fixed withrelation to the base A, ari unnoticed movementof the infant whileadjusting the second ele-ment C causes an inaccurate measurement to bemade, whereas with a deviceof the character herein described, andvwherein both of the elements B and Care movable relative to the base andto the object placed upon the base, any movement of the infant will notvitiate the correct or accurate reading ofthe measuring device for thereason that both of the elements B and C are brought in contact:

with the infant substantially simultaneously by -the operator and thereadii'ig can be quickly and accurately made at the time of suchcontact. l

Having fully described my invention, what I claim is:

l.' A measuring' device comprising a base, a plate slidably mounted onthe base and of substantially greater length than said base,' acahpering element secured to one 'end ofv the plate and adaptedto bemoved toward or from an end of the base, the plate beingl provided withmeasuringY indicia, and a second caliper-ing` element slidably mountedon the base and provided' with an indicator adapted to cooperate withsaid indicia, whereby the .length of an object placed.V upon the baseand extending` beyond one end thereof may be accurately measured bycontact of said calipering elements against opposite ends of the objectrespectively.

` A measuring device comprising a base, a plate slidably mounted on thebase and of greater length than the base, to permit the plate to extendbeyond the ends thereof, a caliperinn' element secured to one end of theplate and adapted to be moved toward or from an end of the base, themovement of the caliperine; element beinev limited in one direction byits abutment against the end of the base, and a second caliperingelementslidably mounted on the base whereby the two elements may besimultaneously adjusted from one end of the base to determiiu` themeasurementof au object placed thereon, and wherein a portion of theobject may extend beyond one end of the base.

' 3.- A measuring device comprising a buse, a plate slidably mounted onthe base and ot substantially greater length than the base, a caliperingelement secured to one end 1of the plate and adapted to be moved beyondan end of the base, and a second calipering ele-- ment slidably mountedfrom the sides of the base and extending across the base over the plate,whereby the two calipering elements may be simultaneously moved from oneend of the base into contact with an object placed on the base betweenthe calipering elements.A
